(Cl. 14S-27) 6 Claims.

This application is a division of my copending application for Apparatus for sorting fruits, liled June 30, 1942, Serial No. 449,116.

This invention relates to apparatus for feeding, aligning and pitting olives and the like.

The main object of my invention is to provide an eiliciently combined apparatus capable of receiving olives and other oval or elongate fruits having removable pits, feeding them to special aligning rollers and pitting said fruits while aligned therewith upon said rollers.

A further object is to have a compact apparatus for the present purpose which requires a minimum of attendants and occupies a minimum amount of oor space, while requiring a minimum outlay of funds ior a maximum output of pitted and sorted olives or other product of this class.

It is also an object to provide apparatus of this character indicated which is so positive and effective in its operations that only a very small percentage of the fruits or berries handled are injured, While the major portion is perfect and of the highest quality.

Other objects and the advantages of my invention and its actual use in practice will appear more fully in detail as this specification proceeds.

Throughout the views, the same references indicate the same or like parts.

In the fruit and berry handling art, and particularly in apparatus for handling such berries and fruits as cherries and. the like, certain operations have heretofore been carried out by hand and while others have been elected by separate machines. This has entailed repeated rehandling of the cherries at various stages and the use of a considerable number of attendants. This involves expense, inconvenience, and the use of a great amount of iioor space, all of which greatlyincreases the cost of the nal product.

In orer to overcome these disadvantages, and particularly with the foregoing objects in view it is now proposed to carry out in a combined machine the entire group of operations required to pit and deliver cherries andthe like from the original clusters.

Hence, referring now again to the drawings in Figs. l to 5, a fruit or berry handling machine, generally indicated at I has a main frame 2 upon which are fixed bearings 3, 3 for a main drive shaft 4 (driven by a motor or other means not shown) having a pulley 5 fixed thereon and connected by a belt 5 to a pulley 1 on one end of a second shaft 8 supported in bearing 9 on post I0 secured on the frame 2. On the other end of this shaft 8 is fixed a stud pinion II meshing with a ring gear I2 on the periphery at one end of a grading drum generally indicated at I3. This drum is supported in inclined position upon a group of grooved rollers I4, I5, etc., carried on an arm I6 on a second post I1 and on further supports I8, I9, etc., on the machine frame, the drum having spaced peripheral rails 20, 2|, etc., riding in the grooves of the rollers and thereby locating said drum in position while allowing the same to rotate on said rollers.

Forming the first or introductory portion of drum I3 is a de-clustering section 22 which is located at the higher end of the drum, immediately within a hopper 23 supported closely adjacent said end of the drum by a 4bracket 24 secured to post I0 and by an extension 25 upon the second post I1 already mentioned.

A further bracket 25 extends from the hopper toward the edge of the drum and meets with an upward extension 21 upon post I0 in order to support a stationary bracket 28 which has an upper cutting blade 29 extending horizontally toward the periphery of the drum and a movable knife or cutter 38 dove-tailed at 3l, 32 to the first blades so as to be slidable with respect to the same in the axial direction of the drum. In order to operate the cutter constituting this construction, the edge 33 of the de-clustering portion of the drum has a series of projections 34, 34 which during `rotation of the drum as a whole engage with a finger 35 fixed on a rocking shaft 36 mounted in bearings 31, 31 on bracket 28 and carrying at the other end an arm 38 having a pin 39 projecting into vertical slots 40, 40 in the lugs 4I fixed to the lower portion of the cutter or blade 38. When the cutter has been operated in one direction to cooperate with the upper cutter 29 so as to shear off the branch connection between the stems in the cluster of cherries by contact of finger 35 with a drum projection 34', a return spring 42 attached to the lower portion of plate 30 at one end and at the other end to a post 43 on bracket 23 willy cause the cutters to separate ready for the next cutting operation. As best seen in Fig. 4, each cutter member 29, 30 is combshaped to form a multiple cutter, the movement being limited by, and the cutters further retained in association by retaining studs 84 on the lower fixed multiple cutter plate 30 extending up through operating slots 85 in the upper movable multiple cutter member 29.

In order to cooperate with the cutters, a group of rigid arms 44 extend radially inward from the interior of the de"clus`tering section of the drum and are so disposed that each group is arranged along a line upon the drum in parallelism with the axis thereof within each one of the projections 34. These arms serve to pick up individual clusters of cherries and expose the stems of the same at the proper moment to the cutters 29 and 30 when they are temporarily open, so that the connection between the stems in each cluster will be snipped oil? by the closing ontthe cutters. When the stems of the cherries have thus been separated, the latter with their individual stems intact will gradually feed down along the grading sections 45 to 49, due to the rotation of the latter and slight inclination of the same, so that the cherries will travel within said drum until the section is reached wherein the holes 50, etc., are sufficiently large to allow these cherries to drop through. As grading drums for various purposes are well known, it will suffice to mention that in this section 45 the holes 5I are the smallest in the series, while the holes or apertures in the succeeding sections are increasingly larger with the holes 52 in section 49 largest of all. It may be added that the apertures in the grady ing sections are, of course, placed all about the drum so that the fruit dropping through the same will fall upon a series of predetermined points of a slidable reciprocating feed plate 53 having rollers 54 resting upon a supporting plate 55 supportedfupon posts 56 and I1. Below the drum an apron 51- and a stem retainer 58 have the upper surfaces inclined in converging manner generally toward the initial location of row of apertures 59 in the feed plate serving to catch falling cherries 50 therein. It may be staterLthat always the cherries 60 will fall inxsuci position that when they drop into apertures 59 in the mentioned feed plate their stems 6I will be directed generally upward. To the lower end of the feed plate is connected a link 52 at 63 which in turn is connected to"and driven by a bar 54 fixed upon a sliding shaft supported in a bearing .55 in post I0 while a cross head r61 connects said shaft with an eccentric ring 68 mounted upon an eccentric 69 iixed on drive shaft 4.

From the foregoing it is clear that upon rotation of the drive shaft the eccentric 59 will cause shaft 65 to reciprocate in bearing 55, and thus through bar 64, and link 62, drive the feed plate 53 upwardly along the support 55 until apertures 59 will register with the upper end of a row of tubes 18 which open in predetermined position through support plate 55. However, when the cherries have been brought part of the distance toward these tubes, the stems thereof will make contact with an entrance portion beneath stem retainer 58 which will-tend to turn down the stem due to the movement of-the feed plate 53 and wipe said stems under said stem retainer, so that each cherry that has a stem is virtually suspended upon the feed plate by the stem above the corresponding tubeA 10 during movement of this feed plate until said plate has movery the cherry beyond said tube 10 to one of a series of rear feed tubes 12. Any excess cherries upon the plate above the one deposited in cherry aperture 59 will be brushed off bythe downwardly directed brushes 1I (Fig. 7) mounted at the entrance portion of the stem retainer, and due to the sharp inclination of the feed plate, such excess'cherries will roll back to the initial position of the cherry aperture, ready to drop into the same during a succeedingcycle of operation of the feed plate. The cherries having stems will thus be carried by the feed plate past tube 1l, but should any cherry have lost its stem, the stem retainer 58 will not operate to suspend the cherry in the aperture 59, but said cherry will instead drop from said aperture down through tube 18 to a collector 13 below the machine. At a point approximately above tube 1l, the stem retainer terminates so that when the cherries which have been carrrkd past tube 10 reach tube 12, the stem retainer no longer retains the stems lying upon feed plate 53, but frees the same so that these cherries may drop individually in said tubes 12,

down into individual troughs 14 in a trough member 11 forming part of a de-stemming device generally indicated at 15, each trough having resilient rubber side walls 16, 16 for gently retaining the cherry in central position within the trough, the troughs in each case being open in front and above.

The lower end of each of the feed tubes 12 preferably terminates a short distance above the xed trough member 11 forming the backingof the resilient walls 16, 16, while between said lower end and said walls is located a slidable open frame 18 supported upon these walls and disposed in an inclined position for a reason" that will immediately appear. As the frame 18 is slidable downward in inclined direction in order to function, the same has retaining springs 19, 19 secured thereto and anchored to the posts |1, etc., of the machine in order to prevent downward movement of said frame until the same positively operated, as may be seen in Figs. 3, 8 and 16. Slidably associated-with the mentioned frame is a de-stemming plate 80 which has a peaked opening 8| arranged substantially above each trough, while the peak or apex 82 is located centrally with respect to the trough walls so that the opening will be symmetrical with the corresponding feed tube 12 in each case. The plate 80 is arranged to slide in side slots 83 in frame 18, which terminate at |82, |82 to form stops for plate 80 against which the plate will engage to operate and move said frame positively and bring the same down into a final position shown in Figs. 10 and 11. It is, of course, intended that the openings 8| in plate 80 shall register with the corresponding feed tubes and troughs, the latter as a group in trough member 11 being rigidly mounted on a pedestal 86 fixed on the frame of the machine.

It may be mentioned here that, as will presently be described, the movement of plate 80 will direct or bend the stem 6| of each cherry forward or out from its respective trough, and in order to provide clearance for long stems, each feed tube 12, has a pair of vertical projecting front lipsv or edges spaced apart to form a slot to allow such stems to be drawn forward freely without meeting any obstruction.

At the ends of plate 80 are secured pivot pins 86,- 86 projecting into slots 81 in levers 88, 88 pivoted intermediate their extremities at 89 to xed portions of the machine, as for example to the trough member 11. To the other ends of these levers are connected further levers 90 (Fig.

l 3) pivoted at 9| and in turn connected at their lower ends to the rear ends of long links 92, the latter being pivotally connected at their forward ends to the bar 64 reciprocated by the eccentric as already described. Upon this bar are also mounted a series of pit punches 93 directed rearwardly toward the trough member 11, while rearwardly of said latter member are a second series of pit punches 94 entering the individual troughs through rear apertures 95, while being slidably supported in bearings 95. The last mentioned punches 94 are connected to a bar 91 and cam rollers 98 operating on cams 99 fixed to shaft rotated in synchronism with shaft 4 by means of a chain |0| engaging with sprockets |02, |03 fixed upon shafts 4 and |00 respectively. A short distance in front of the trough member 11 is a stop member |04 with a cavity |05 facing the troughs 14, 14 and having apertures |06 through which punches 93 may be projected during operation. Between the cavities and the troughs is a forked gate means |01 swingably suspended upon member |04 at |08, there being a downwardly open slot in said member |01 for each trough through which the corresponding forward and rear punches may project. Below the trough member 11 and stop member |04 is a chute 8| through which pitted 'cherries are intended to fall from the space between the trough member and the stop member, said chute extending down to a raised horizontal portion |0 of a conveyor generallyindicated at operating with portions thereof in a water tank 2 and driven by a roller ||3 rotated by a pulley ||4 from a pulley ||5 through a belt ||6. While the tank is shown as disposed beneath the machine,

'the rear portion thereof is intended to be suiliciently extended to project beyond the rear posts ||1 of the machine frame 2.

The upper horizontal portion ||0 of` the conveyor operates at slightly higher level than the level ||8 of the -water in tank |I2, while an inclined partition ||9 extends downwardly from a short distance below the water level at the entrance portion of the tank toward the outlet portion in the rear, while a downwardly extending portion |20 and a lower horizontal portion |2| ofthe conveyor pass beneath said partition and beyond the rear lower end thereof. The upwardly inclined portion |22 of the conveyor rises to pass over roller |23 and then down at |24 and beneath the tank at |25 and thence up again at |26 over roller I3.

Following the cycle of 'operations in even better detail from the hopper 23 to the conveyor Il,

it may be assumed that a\more or less continuous supply of clusters of cherries are fed to the hopper whence the clusters feed in by'gravity from said hopper 23 to the interior of the declustering section 22 of the grading drum I3, the latter being rotated clockwise in Figure 3. The clusters are picked up by the inwardly extending pins or arms 44 and as each cluster is caused to pass the bracket 28 and the cutters 29 and 30, the cutter 30 being operated through arm 38, rocking shaft 36 and contact of nger 35 on said shaft with projection 34 on the drum. y

As shown in Figure 5 the connecting branch portion |21 of the cherries 60 will be cut on from the stems 6| while said branch portion is momentarily held on the arm 44 when the cherries will drop to the drum in lseparated condition. These cherries then gradually roll inward from the declustering section into the grading sections 45 to 49 to drop through the apertures 50, 5|, and 52 as the case may be according to their sizes, and thence into the apertures 59 .of feed plate 53 reciprocated from eccentric 69 through bar 64 and link 82, when these cherries will be passed to and drop into feed tubes 12 and deposited in troughs 14 as shown in Figure 8. As diagrammatically shown in Figures 9 through ll, etc., when the cherries have reached the troughs, the apertured plate will be drawn down over the cherries in the troughs by levers 88 through further levers 90 and links 92 so that the stems of the cherries will be centered in the upper apices 82 of the peaked apertures 8| in the plate 80 will engage the lower ends |82 of slots 83, 83 in slidable frame 18 to draw the same positively downward upon the walls of the troughs, the apex portions of the peaked apertures of plate 80 pinching thestems against the lower edges |28 and turning the cherries by means of their stems to face punches 93 and drawing the same forward between resilient side walls 16, 16. During the downward movement of the slidable frame a rockable cherry thereof to swing down against the cherry, preventing the same from being pulled out of the trough. While member |28 thus holds the cherry 80 in place the plate 80 and slidable frame 'I8 continue moving downwardly in inclined direction. and due to the fact that the stem 6| in each case is pinched between the apex portion 82 of the plate 80 and the edges |28 of the slidable frame, said stem is pulled free from the cherry as shown in Fig. 10. In this position the plate is in its lowest position with the lower portions |88 thereof projecting a distance beyond the slidable frame 18, said lower portions forming stem strippers as will immediately be explained. The blocks |30 just mentioned when stopped against the lower end |84 of slots |85 will not prevent the slidable frame or the plate from continuing as the only actual connection between the two is one or a group of springs |81 which tend to draw the block |30 down close to the plate. Stripper portions |86 of the plate will upon rear movement of the latter pass between the edges |28 and strip away the stems 6| which may remain between said edges while upwardly directed brushes |33 tend to engage the released stems and prevent the same from following any oft-he parts upon the slidable frame in the upward rear movement. but will rather cause the stems to remain behind and drop down from the brushes to be discarded as partly shown in Fig. l1.

When slidable frame A18 approaches its lowest limit of movement a projection |88 on the lowest portion thereof will engage a resilient pivoted stop |88 and by virtue of the spring |80 connected to one end of said pivoted stop and the bracket |8| projecting forwardly fromftrough member 11 sothat said resilient stop will snap past the frame stop |88 and tend to partly impede or delay return movement of the frame upwardly upon the trough member. The effect of the break or stop thus described is to provide a suillcient time for the descent of the de-stemming device and allow. the cherry to be drawn forward between the rubber wall 16 and de-stemming device and also the stems stripped from between edges |28 before the slidable frame again returns upward to initial position. During return movement of frame 18 the return iinger |3| of cherry holder |29 is of course removed from contact with ilxed stop |32 and block stop |83 from contact with end stop |84, which allows a spring |34 to draw the upper projection |35 of member |28 toward the lug |38 fixed upon block |30 thus swinging member |28 up and away from the cherry.

With the cherries in place as just described, the rotation of eccentric 68 and simultaneously cam 88 the punches 83 are caused to pass through apertures |06 and stop |04 to meet with the pit |31 within the cherry 60, as particularly shown in Figure l2, after which rotation of the cam 88 and eccentric 08 will cause the cherry thus impaled upon both forward and rear punches to be moved from its trough to pass gate |08 into cavity or channel |05, the gate once passed swinging down beyond the cherry as shown in Figure 13. At this moment each punch 84 continues through the aperture |06 in stop |04, while the cherry 80 remains in cavity |05, the stop plate virtually acting as a die plate for the cherry, while the punch pushes the pit |31 out through said aperture and down upon the outer or forward side of the stop as particularly shown in Figure 14. Inaslnuch as stones or pits in cherries vary in size, the punches 83 and 84 are, of course provided with means for resiliently compensating for such dill ferences and avoiding crushing or breakage of the pits. Thus, the punches 83 have a resilient spring take up portion 83' of more or les conventional construction which allows these punches to yield a little for larger sizes of pits and t0 project further for smaller pits. When the punch 83 and also punch 8411s withdrawn, as shown in Figure 15, the cherry is withdrawn against gate |08 by punch 84 but is stopped by said gate so that the` punch is` fully withdrawn from the cherry 60, thus freeing the latter to fall down into chute |8| when the members already described will be immediately ready for another cycle with fresh cherries just dropped from the grading drum.

As already mentioned the horizontal upper portion of ||0 of the conveyor receives the pitted cherries from the chute |8| and as this operates toward the right in Figure 3 indicated by the arrow within pulley ||4 these cherries are fed to-the surface ||8 of the water upon which all sound pitted cherries will iloat toward the rear roller |23 above the rear end of the water tank ||2. However, a counter-conveyor |38 operating toward the left as indicated by the arrow above the horizontal portion |38 in Figure 3 would hy virtue of its hooks |40 pick up the iioating sound cherries and convey the same upwardly upon its inclined upper stretch |4| toward roller |42 at which point these cherries will be released upon an inclined table |43 having a lower apron |44 allowing the cherries to slide down into a cart |45 for collecting the same. In order to operate conveyor |38, the roller |23 has a pulley |48 provided With belts |41, |48 rotating roller |48 and pulley |50 of roller |42, the roller |23 being o! course operated by the conveyor belt Perfeet pitted cherries are light and therefore float in water, while Vbroken ones sink, the perfect cherries containing air.

During operation it is possible that some cherries are of such unusual form or have defects so that when they are passed through the machine they are either mutilated and broken or perhaps missed by the punches so that they are not prop'- erly pitted, and al1 such cherries as they fall through chute |8| will upon being deposited upon the water at ||8 immediately sink down to partition ||8 and gravitate toward the lower end thereof, at which point they will be caught by the upwardlytraveling portion |22 of the conveyor and brought over roller |23 and deposited upon a horizontal belt |5| which is preferably made of translucent or transparent material, for example, of cellulose acetate or a derivative thereof, or even a plastic of the vinyl series. This conveyor operates upon a pair of rollers |52, |58, the first having a pulley |54 connected to a pulley |46 of roller |23 by means of a belt |55, the rollers |52 and |53 being supported upon a frame |58, while within the belt is a series of electric lights |51 illuminating said belt from within so that cherries carried forward on said belt in the direction of the arrow immediately above same will be readily inspected by an operawr inspecting said belt to discover cherries which still retain their pits. Such cherries will easily be seen because they will be relatively opaque, while the pitted cherries will be translucent. The

' unpitted cherries can thus be easily picked oil! rmay be used without others, or be replaced by others of modified form, it is quite evident that if clusters of cherries are fed to the hopper 23, unpitted cherries having no stems ywill be dropped through tube 10 into the collect'or cart 13, the pits dropped upon the upper portion or roof |60 of the chute |8| to fall into a collector cart |6I, while the perfect pitted cherries will be collected in collector cart |45 and the broken cherries in cart |58, and the operation will be continuous and wholly automatic throughout. In this connection it is to be noted that the machine is suitable not only for pitting cherries, but also for pitting plums, apricots and other freestone fruits and berries, particularly such as have stems. n the other hand, this machine is equally well adapted when slightly modied for pitting olives and other fruits, which usually do not have any stems, but instead are of more or less oval or ovoid form. When olives are to be pitted the de-stemming apparatus as well as the de-clustering mechanisms are of course not necessary, but another expedient may be incorporated in the machine to replace the de-stemming device 15, as particularly shown in Figures 18 and 19.

As shown inFig. 7a, the feed plate 53 for use with cherries may be replaced by a feed plate 53' reciprocating above stationary plate 55 having only a single row of tubes 12 (one shown) for receiving the olives |69 instead of the two rows of tubes connected to plate 55 of the cherry feeding device described.

Thus, the olives are fed along by plate 53 to drop into the feed tubes 12, 12 which do not surmount the trough members as before, but rather terminate adjacent to lthe upper surface of a pair of rollers each at |62, |63, which are horizontally arranged and rotatably mounted upon bearings |64 ilxed upon a general support |65 which may be part of the fixed frame of the machine. Pulleys |66, |61 on these rollers are all in contact with a belt |68 obtaining its drive from the main drive shaft 4, or the rear shaft |00 by gearing |93, |94 and belt |98 engaging with a pulley |96 on shaft |95 also carryingV |94 and also engaging pulley |91 on vdrive shaft 4, the same parts being conventional as such details form no part of the actual invention. The rollers may be driven in opposite directions as indicated by the arrows, or in the same direction if desired, the main point being that both rollers associated with each feed tube rotate simultaneously so that when an olive |69 is deposited through the tube upon. one pair of these rollers the rotation thereof will immediately cause the olive to line up its axis |1| parallel to the rollers as shown at |10.

Cut-away portions or apertures |92 may be formed in the lower ends of the tubes to provide clearance for the punches, and it is readily noted that rear star punch 94 is disposed in substantial alignment with the center |1| of the olive so that when the same is operated said olive will be freed from its pit by the rear punch 94 forcing the pit |12 into a hollow front punch |13 when the olive has been carried by both punches into contact with the cavity and stop |04 beyond gate Y |09, as particularly shown in initial fashion in Figure 19. A spring operated ejector |14 tends to remove the pit from within punch |13 as soon as the olive has dropped behind the gate when freed from the punch, the-olive then appearing as shown in either of Figures 23 or24 at `|15 with a pit removed from the stem end |16 or from the other end |11.of olive |18. The ejector |14 mayomit the spring and a stop or other device may be used to operate or hold the ejector to expel the olive pit upon retraction of punch 13.

In Figure 21 a section is shown of one of the feed tubes with its associated rollers beneath the olive being also shown in position, while the rollers are particularly shown as being cylindrical in form. The rollers may of course be modied so as to assume a concave form at |19, in Figure 22, or any other profile may be adopted to suit the sizeand shape of the fruits to be handled.

Manifestly other variations may be resorted to, such as for example, the diierent sizes and shape of cutters for de-clustering and different forms of arms upon the ,de-clustering section of the drum, etc., may be adapted to suit conditions.

From the foregoing it is clear that a group of operations are performed by the machine Without necessarily including any handlabor for transferring separated cherries to any destemming apparatus or the de-stemmed cherries to pitting apparatus, etc., but rather all operations succeed each other rapidly and automatically in order so that a constant supply of clusters of cherries or other fruit to lthe hopper 23 will produce a supply of pitted cherries or other fruits in the collecting carts upon the floor level below the machine, while stems and pits, etc., and broken fruit will be segregated.
